WILLIAM S. HAMM, OF LAKESIDE, ILLINOIS.

LANTERlE-I-BURNER.

Specification of Letters Patent.

Patented April 27, 1909.

Application filed April 8, 1907. Serial No. 366,998.

To all whom "it may concern:

Be it known that 1, WILLIAM S. HAMM, a citizen of the United States, andresident of Lakeside, county of Cook, and State of Illinois, haveinvented certain new and useful Improvements in Lantern-Burners, ofwhich the following is a specification, and which are illustrated in theaccompanying drawings, forming a part thereof.

The invention relates to lantern burners which comprise a wick-tube anda wick raiser in the form of a star wheel carried by the shaft.

The object of the invention is to render the wick raiser more certain inits action, particularly for the purpose of preventing the descent ofthe wick due to jarring or violent motion of the lantern; and itconsists in means for frictionally holding the star wheel or its shaftagainst rotation, and, more specifically, in a spring yieldingly forcingthe shaft against its hearing.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is a side elevation of a burner, a portion of the wick beingshown; Fig. 2 is a side elevation of the same from a different point ofview; Fig. 3 is a sectional view on the line 3-43 of Fig. 1, the wickbeing omitted Fig. 4; is a side elevation of the burner, partly insection, showing a modified form of construction; and Fig. 5 is asectional view on the line 5-5 of Fig. 4, the wick being omitted.

The burner head is represented at 10 and comprises a chambered body,preferably of sheet metal, having a threaded shank 11 for engagementwith the lantern font, not shown. The wick-tube 12 extends entirelythrough the body 10, projecting downwardly a suitable distance to guidethe wick, and upwardly a suitable distance in order that the flame maybe maintained in the proper position in the lantern body.

When a fiat wick tube is used, as in the construction illustrated, aplurality of star wheels 13, 14 and 15 aroused to raise the wick, andare fixedly mounted on a shaft 16 projecting through the body 10 andbeing adjacent to the wick tube, the latter being apertured to permitthe star wheels to project into its chamber. A grip 17 is applied to theouter end of the shaft to facilitate its control.

A bowed spring 18 is fitted within the chamber of the body 10, its endsbearing against the shaft 16, as shown at 19, 20, and its crown bearingagainst the side of the body, as shown at 21.

As illustrated in Figs. 2 and 3, the apertures in the walls of the body10 within which the shaft 16 is located, are somewhat larger than thediameter of the shaft, permitting the latter to be forced, under theinfluence of the spring, against the side wall of the tube 12, so thatits bearings consist of the tube wall and the spring ends. By this meansa long bearing is provided for the shaft in the Wall of the wick tube,and the spring ends are so shaped, as represented at 19, 20, toconstitute bearings of considerable areas, there by reducing the wear onthe shaft and its bearings to a minimum.

The spring is contractile in character, that is to say, its elasticitytends to urge its ends toward each other and hence, when fitted withinthe burner body, it forces the shaft toward the wick tube.

It is important that the shaft bearings be prolonged, and this ispreferably secured as above described and as illustrated in Figs. 2 and3. Other means, however, for providing an extended bearing, in lieu ofthe wall of the wick tube, may be provided, as, for example, theprotruding lips 22, 23, formed around the apertures in the body 10,which accommodate the shaft 16, as illustrated in Figs. l. and 5, suchapertures in this case being so disposed that that side of therlipswhich is opposite the spring 18 constitutes the shaft bearing, holdingthe shaft out of contact with the wick-tube.

While I have shown and described a wicktube extending entirely throughthe body of the burner and a star wheel device for raising the wick,taking the form of a star wheel, it will be understood that theinvention is applicable to any form of burner in which. there is a wickpassage and a star wheel operated by a rotatable shaft for raising and.lowering the wick.

I claim as my invention- 1. In a lantern burner, in combination, a

chambered body, a wick-tube, a star-wheel projecting into the tube, ashaft continuously bearing against the wick-tube and carrying thestar-wheel, and a leaf-spring located within the body and reactingbetween the inner walls thereof and the shaft shaft to yieldingly holdthe latter against the to yieldingly hold the latter to the outerWick-tube, the ends of the spring being pro- 3 wall of the wick-tube.longed parallel with the shaft to form ex- 2.
